As plans got under way for the Allied invasion of Sicily in June 1943, British head of counter-intelligence Ewen Montagu masterminded a scheme to mislead the Germans into thinking the next landing would occur in Greece. The innovative plot was so successful that the Germans moved some of their forces away from Sicily, and two weeks into the real invasion still expected an attack in Greece. This extraordinary operation called for a dead body, dressed as a Royal Marine officer and carrying false information about a pending Allied invasion of Greece, to wash up on a Spanish shore near the town of a known Nazi agent.

Montagu tells the story as only an insider could, offering fascinating details of the difficulties involved especially in creating a persona for a man who never was and the risks involved in mounting such a complex operation. Failure could have had devastating results. Success, however, brought a decided change in the course of the war.
